[U-Boot] [PATCH 2/3] sandbox: allow processing before main loop

[Mike Frysinger]

From: Simon Glass <sjg at chromium.org>

In order to pass command line arguments to sandbox we need to be able
to act on them. So take control back at the end of board_init_r() from
where we can call the main loop or do something else.
